This guide illustrates how to create site navigation with no drop menus at the top level and never use a side navigation menu on interior pages. By way of example, check out School Loop's website. Also see our Easy Start Guide: Minimalist Top Navigation for a variation on this theme.
Step 1: Login and work your way to the Site Center
Step 2: Create The Top Level Menu Options
The key to this style of menu is to only create pages at the top level. Do not add Navigation Headers or Minisites. You may use a Link if you wish to have a top level menu option that links to an external site.
Be sure to choose one of the page layouts that does not include the side navigation menu when creating your top level pages.
Step 3: Create a Hidden Folder for all other Content
Create a hidden folder at the top level along with the pages created in steps 2. The name of this folder is not important, so you might as well name it "Hidden" just to keep its purpose clear.
In this hidden folder, you will store all the other pages used on your site. The pages at the top level of this folder will never display the side navigation menu, so you may choose any of the page layouts picture above. If you nest other folders for organizational structure, also create those as hidden folders to ensure you will never see navigation on the side of any page.
